CORN-PLANTER ATTACHMENT.

SPECIFICATION forming part of Letters Patent No. 460,159, datedSeptember 29, 1891.

Application filed July 20, 1891. Serial No.400,036. (No model.) i

To all whom it may concern;-

1% it known that I, JOSEPH B. PEDEIOK, a citizen of the United States,residing at O0- lumbus, in the county of Bartholomew and State ofIndiana, have invented a new and useful Improvement inCorn-PlanterAttachments, of which the following is a specification.

My invention relates to an improvementin an attachment to thefurrow-runner of a cornplauter for the purpose of scraping away thesurface-soil on each side of the furrow, for which Letters Patent No.333,5 l1 were issued to me January 5, 1886. Said attachment consists ina pair of diverging plates united at their forward ends and secured tothe runner and extending beyondthe rear end there of, so as to form awider second furrow above that in which the corn is to be dropped.

The object of my present improvement is to provide improved means forsecuring to the runner the plates which form the second furrow.

The accompanying drawings illustrate my invention.

Figure 1 is a plan showing the attachment in position on thefurrow-runner. Fig. 2 represents a side elevation of the same, havingone of the plates removed. Fig. 3 represents an elevation of the innerside of one of the attached scrapenplates. Fig. 4 is a rear'elevation.

In the drawings, A designates a casting, having on its under sidealongitudinal groove 13, which fits over the back edge of thefurrowrunner O of a corn-planter. Extending radially from the part A area pair of radial arms D D, each having in its outer face a broadvertical groove E, having a serrated surface F. The central part A andarms D constitute a saddle, which is secured to the furrowrunner in afixed position by a set-screw G.

H H are a pair of thin steel plates slightly curved longitudinally, andeach having secured to its convex side, near one end, a raised plate I,having a serrated surface J, corresponding to the serrated surface F,and a central vertical slot K, the sides of which are undercut, so as toreceive and retain the head of a bolt L, which passes through the arm D.Plates H H are each secured to the saddle A by means of the bolt L andthe interlocking serrations F and J, so as to be vertically adjustablerelatively to the runner. By this construction the saddle or body of thedevice may be secured to the furrow-runner in a fixed position, and theplates H H may be quickly adjusted, so as to leave the furrow of agreater or less depth Without disturbing the position of the saddle.

I claim as my inventiou- The above-described corn-planter attachment,consisting of the saddle having in its under side a central grooveadapted to embrace the upper edge of a corn-planter runner, and theradial arms D D, said arms being each provided with a groove E, serratedsurface F, and bolt L, and the plates 11 H, each provided with aserrated plate I, having the undercut slot K, all combined and arrangedto co-operate with each other and with the furrow-runner of acorn-planter, substantially as specified.
